If you want a lot of information in one book take a look at Gary Reeder's book on handgun hunting. I bought his original and updated book when I was visiting Arizona with Ron from the CF in 2013. A lot of good information from someone who has been there and done that.
As to "what gun", depends on you. Some people like the challenge of a open sighted revolver....some use a stockless rifle like an Encore...no right answer.
